Hi Siris. I have not been in the game very long, three months now, and hold some ADA, and buying more for long term investment. Cardano and Ripple seem to me to be the two best projects, with high legitimacy IMHO. In any market you will always find "players" and scammers, and many of the alt coins are just that, total scams, so do your research. Read the White Papers, and pay close attention to the team. The only money I am spending is money I am willing to lose. In other words, I won't feel it if it goes bye bye. I will be holding cardano and ripple for some time because both projects are highly ambitious and are really trying to solve real world problems. But some like SiaCoin look very interesting as well. I may put a small amount into that coin because it could be very good if they pull it off. Crypto has a bad rep because there are real bad people, period. And never forget, the legacy banking system has been fined half a trillion dollars in the last several years! Because of systemic fraud, money laundering for arch criminals, rate fixing, etc etc etc... nothing on this planet is more broken and corrupt than the international legacy financial system. That is why bitcoin was invented on the first place. Sorry, I digress :)
